Calculate (show calculation) the pH of a solution prepared by mixing 100 ml of 0.1 M formic acid and 5.0 ml 1N NaOH, pKa = 3.65? The answer is pH 3.65, show the calculation.
Your supervisor asks you to prepare 474.00 mL of ammonium buffer solution 0.1 M with pH= 9.00, from a concentrated ammonia solution (16%w/w, d=0.98g/mL) and solid ammonium chloride (97% w/w). (MW of NH3 = 17.031 g/mol and FW of NH4Cl = 53.491 g/mol and pKa NH4+/NH3 =9.24). How many grams of the solid ammonium chloride do you need? Consider two decimal places for the answer.
What is the pH of a solution containing 0.50 M ammonia and 0.50 M ammonium chloride? What will the pH be after 25mL of 0.20 M of hydrochloric acid has been added to 100.0mL of the solution containing the ammonia and ammonium chloride? What will the pH be after 18mL of 0.25 M of lithium hydroxide has been added to 100.0mL of the solution containing the ammonia and ammonium chloride? The ionization constant for ammonia is 1.8x10-5.
